I am happy with this product but if you have a large cot or cotbed, bear in mind that this it doesn't go all the way round. There are two sections and each covered a long side and about half a short side in our cotbed. We had a problem as our short sides are solid so there were no bars to put the ties on. We are using a fabric cot book we already had to make up for the shortfall and have tucked the short side bits into the mattress but not ideal as baby pulls it out frequently.
just a bit disappointing that the top comes off so easily. There I was trying to show my baby how to fit the blocks through the holes and she took off the lid and put them in that way instead!
